A metal smelting apparatus for smelting a metal such as copper or aluminum is an apparatus for manufacturing a desired shape by melting metal through an electric arc or gas of high pressure and high current.

In order to melt various kinds of metals, the temperature inside the smelter is usually controlled to be maintained at a high temperature of 1000°C or higher.

In recent years, useful metals are often melted and extracted from electrical and electronic components such as PCBs for efficient recycling and reuse, and research on related technologies is being actively conducted.

The flow pipe fixing member 30 is disposed on the base member 20, and is vertically disposed to form a space S2 separated from the inlet 2 in the outer body 10 inside.

The separation space S2 is formed between the inlet 2 of the outer body 10 and the flow pipe fixing member 30 as described above, so that the gas introduced through the inlet 2 is transferred to the flow pipe fixing member ( 30) can be distributed over the entire area.

A flow pipe 50 is coupled to the flow pipe fixing member 30 , and the other end of the flow pipe 50 is coupled to the cooling dust collecting member 40 .

The flow pipe 50 may be formed of a synthetic resin material such as flexible heat-resistant silicone, and wrinkled portions 52 are formed to enable flexible bending.

Here, the surface of the flow pipe 50 may be formed with a metal coating including aluminum or silver component.

Thus, the heat conducted to the flow pipe 50 is smoothly dissipated through the metal coating part.

The cooling dust collecting member 40 is formed of a metal material, and is arranged in a plurality of rows and columns on the base member 20 inside the outer body 10 .

Compared to the conventional dust collector formed as a large silo, in a state in which the cooling dust collecting member 40 is formed in a small size with a metal material, the gas is disposed in a plurality of rows and columns inside the outer body 10 By being configured to pass through the cooling dust collecting members 40, the contact area with which the high-temperature gas from the melting furnace is contacted for cooling can be significantly increased.

That is, in the case of a large silo, since the internal space is very large, a phenomenon occurs that the gas does not sufficiently contact the wall surface of the silo during the flow of gas.

As described above, when the wall surface of the silo cannot be contacted, cooling by heat conduction cannot be achieved, and only heat transfer cooling by convection can be achieved.

However, when the gas is cooled through heat transfer by convection, the efficiency is significantly lowered compared to cooling by conduction, and due to this phenomenon, the gas that has not been sufficiently cooled is transferred to a subsequent processing device.

However, in the dust collector according to the present invention, the gas introduced through the inlet 2 is configured to pass through each of the small cooling dust collecting members 40, so that the heat transfer area that can be cooled by conduction is significantly increased As a result, the cooling efficiency can also be significantly increased compared to the conventional cooling by a large silo.

Thus, the gas flowing into the upper cooling dust collecting unit 42 is configured to rotate smoothly along the inner surface of the upper cooling dust collecting unit 42 .

Thus, it is possible to prevent the upper cooling dust collecting unit 42 from being deformed or damaged due to thermal shock when the high-temperature gas shocks the upper cooling dust collecting unit 42 .

In addition, as the high-temperature gas flows in a circular manner in the inner space of the upper cooling dust collecting unit 42, the gas may come into contact with the entire circumferential inner surface of the upper cooling dust collecting unit 42, thereby increasing cooling efficiency. can

In another embodiment of the present invention, corrugations 64 may be formed in the outlet pipe 60 .

A sufficient heat dissipation area may be secured by increasing the surface area of the outlet pipe 60 by the corrugation portion 64 .

In addition, the outlet pipe 60 may have elasticity in the longitudinal direction due to the corrugation portion 64 , thereby responding to expansion due to heat and contraction due to cooling.

After moving along, it can be fixed with a coupling means 432 such as bolts.

With this configuration, the cooling dust collecting member 40 can be easily disposed and repositioned on the base member 20, and can be easily separated and replaced or repaired when necessary.

In addition, the number and position of the cooling dust collecting members 40 can be easily changed according to the processing capacity of the melting furnace.

And, when a failure occurs or is damaged in some of the cooling dust collecting members 40, processing through the remaining cooling dust collecting members is possible, so that continuous work without interruption of the dust collecting work is possible.

In another embodiment of the present invention shown in FIG. 8 , irregular fine concave portions 41 are formed on the surface of the cooling dust collecting member 40 .

The irregular fine concave portions 41 may be formed by sand blasting the surface of the cooling dust collecting member 40, and the surface area for heat dissipation may be further increased by the fine concave portions 41 as described above. can

A thermally conductive coating including aluminum or silver components may be formed on the surface of the cooling dust collecting member 40 .
